there is a tag under the hood Maybe on the compressor itself, support bar for radiator or under the hood.

REFRIGERANT-134A CAPACITY

Utility Models 1.02 kg (2.25 lb.)

• Overcharging a system may allow liquid Refrigerant-134a to get into the compressor, causing compressor noise and damage. Undercharging will cause insufficient cooling.

Refrigerant Oil Distribution REFRIGERANT OIL DISTRIBUTION
The Harrison HT-6 compressor system used on all models requires polyalkaline glycol (PAG) refrigerant oil in the quantities listed below:

• Without Aux. A/C - 240 ml (8 fl oz)
• With Aux. A/C - 330 ml (11 fl oz)

New oil quantities must be added to the system during component replacement and conditions stated as follows:

• With no signs of excessive oil leakage, add:

1. All Compressors (drain and measure the oil)

• • If less than 30 ml (1 fl oz) is drained-add 60 ml (2 fl oz) to the new compressor.
  • If more than 30 ml (1 fl oz) is drained-add same amount that was drained to the new compressor.

1. Accumulator-Add 105 ml (3.5 fl oz) of new oil to the replacement accumulator to compensate for oil retained by original accumulator desiccant and bag assemblies. The accumulator should only be replaced if leaking due to a perforation, damaged O-ring seal seat, or damaged threads.
2. Evaporator-Add 90 ml (3 fl oz) of new refrigerant oil.
3. Condenser-Add 30 ml (1 fl oz) of new refrigerant oil.

REFRIGERANT OIL LOSS DUE TO A LARGE LEAK
If the refrigerant charge is abruptly lost due to a large refrigerant leak, approximately 90 ml (3 fl oz) of refrigerant oil will be carried out of the system suspended in the refrigerant. Any failure that caused a abrupt refrigerant discharge will experience this oil loss. Failures that allow the refrigerant to seep or bleed off over time do not experience this oil loss.
Upon replacement of a component that caused a large refrigerant leak, add 90 ml (3 fl oz) of new polyalkaline glycol (PAG) refrigerant oil plus the desired amount of oil for the particular component.

layman terms = 3 can 12 oz size?

 

[sumo]

gonna have to read the content on the bottle that your gonna use.

 

[delock]

12oz per can

 

[SunlitComet]

Then 3 cans.
